Honestly, in my opinion. There is no need for bigger injectors at this point. The stock injetors can handle more HP than the engine has or can easily be squeezed out of it. If it were me I would do:

CAI - NeedsWings
Tune - TVT
Plugs - NGK Iridium

Thats a good base, but by the same token. A tune isn't really necessary until you get everything else done performance wise that you want. So there are trade-offs...If you still want to do injectors, then I would look into the full TVT250 mod, that comes with everything you want.
